Data caching for cloud services

Abstract

Methods and systems for caching data for resources using a shared cache are described herein. The data may be stored in a configuration service, in the resources, or in the shared cache. The data stored in the configuration service may be modified. The data stored in the resources and in the shared cache may be updated according to the modified data in the configuration service. The data stored in the configuration service, in the resources, or in the shared cache may be used based on an operation mode.

What is claimed is: 
     
       1. A method comprising:
 receiving, by a computing device and from a user device, a request to access a virtual machine; 
 based on a load of a configuration service satisfying a threshold, determining whether configuration data associated with the virtual machine is stored in a shared cache; 
 after determining that the configuration data is not stored in the shared cache, retrieving the configuration data from the configuration service; 
 updating the shared cache with the configuration data; and 
 configuring the virtual machine using the configuration data in the updated shared cache based on the load of the configuration service satisfying the threshold. 
 
     
     
       2. The method of  claim 1 , further comprising:
 after determining that the configuration data is stored in the shared cache, retrieving the configuration data from the shared cache; and

       3. The method of  claim 1 , further comprising:
 determining, based on business hours of an organization associated with the user device, the load of the configuration service. 
 
     
     
       4. The method of  claim 1 , further comprising:
 receiving, within a period of time, a plurality of requests to access virtual machines; and 
 determining, based on a quantity of the plurality of requests, the load of the configuration service. 
 
     
     
       5. The method of  claim 1 , wherein the updating the shared cache with the configuration data comprises:
 after determining that the configuration data for the virtual machine is not stored in the shared cache, sending, to the configuration service, a request associated with the configuration data for the virtual machine; 
 receiving, from the configuration service, a response associated with the configuration data for the virtual machine; 
 determining, based on the response received from the configuration service, the configuration data for the virtual machine; and 
 inserting, into the shared cache, the configuration data for the virtual machine. 
 
     
     
       6. The method of  claim 1 , wherein the updating the shared cache with the configuration data is based on detecting a change of the configuration data stored in the configuration service. 
     
     
       7. The method of  claim 1 , wherein the configuration data for the virtual machine comprises one or more of a Central Processing Unit (CPU) capacity of the virtual machine, a Random Access Memory (RAM) capacity of the virtual machine, or a storage capacity of the virtual machine. 
     
     
       8. The method of  claim 1 , wherein the shared cache comprises an in-memory database. 
     
     
       9. The method of  claim 1 , further comprising:
 after updating the shared cache with the configuration data, replacing the configuration data stored in a local storage of the virtual machine with the configuration data. 
 
     
     
       10. The method of  claim 1 , wherein the configuration data for the virtual machine expires in the shared cache after an expiration period, and wherein the method further comprises:
 based on the load of the configuration service satisfying the threshold, refreshing the expiration period. 
 
     
     
       11. The method of  claim 1 , further comprising:
 receiving, by the computing device, a request to access a second virtual machine; and 
 based on the load of the configuration service not satisfying the threshold, sending, by the computing device and to the configuration service, a request to determine configuration data for the second virtual machine. 
 
     
     
       12. A computing device comprising:
